FAQs
No. This is a strictly "deep cycle" battery designed to provide steady, continuous power over a long period. While the upgraded 250A BMS is incredibly powerful for running heavy-duty household appliances, it is not designed to deliver the massive, instantaneous burst of Cold Cranking Amps (CCA) required to start a vehicle engine. Using it to start an engine will immediately trigger the BMS overcurrent protection and may permanently damage the unit. It should be used exclusively as a "house" or "service" battery to power your electronics and living space.
This battery holds a massive 2560Wh of energy. Thanks to the upgraded 250A Battery Management System (BMS), it can easily deliver up to 3200W of continuous output power. This means it can not only provide over 24 hours of standard runtime but effortlessly power high-demand appliances like RV air conditioners, microwaves, and coffee makers—making it the ultimate choice for camper van travel and off-grid living.
A standard 12V 100A battery can usually only output around 1280W, which often falls short when running heavy-duty appliances. Our Plus version, equipped with a 250A BMS, skyrockets the continuous output power to 3200W—a massive 150% performance improvement! You can run multiple high-drain devices simultaneously without tripping the overload protection, truly making it a performance beast.
The precise dimensions are 521.5 × 238.0 × 220.8 mm, and it weighs approximately 26.4 kg. Compared to traditional lead-acid batteries of the same capacity, it weighs less than half. Featuring a true plug-and-play, zero-maintenance design, a single unit effortlessly does the work of two. Installation takes just 10 minutes, maximizing your precious space.
Absolutely! It features a highly flexible 4S4P expansion system (allowing up to 4 in series and 4 in parallel simultaneously, up to 16 batteries in total). You can easily scale your system up to a massive 48V 800Ah bank, delivering an incredible 40.96kWh of total energy and 51.2kW of output power. Whether for heavy-duty RV use or a whole-home off-grid backup system, it can handle the load perfectly.
It offers ultimate charging flexibility. It is fully compatible with solar panels (requires an MPPT controller), vehicle alternators (requires a DC-DC charger), grid power, and generators. With a maximum continuous charge current of 250A, it can be fully recharged in as little as 5 hours using an appropriate high-output charger.
We use high-quality, EV-grade LiFePO4 cells. At an 80% Depth of Discharge (DOD), it is built to deliver over 6000 deep charge/discharge cycles. Even if you deep cycle it once every single day, its lifespan can easily exceed 10 years, making it an incredibly cost-effective long-term energy investment.
It boasts excellent weather resistance, operating reliably and discharging steadily in a wide temperature range from -20°C to 60°C (-4°F to 140°F), handling everything from severe cold to scorching heat. To protect the internal cells, the safe charging temperature range for all standard LiFePO4 batteries is between 0°C and 55°C (32°F to 131°F).
Featuring a rugged IP65-rated enclosure, this battery is completely dust-tight and highly water-resistant, engineered to effortlessly handle rain, boat spray, and harsh outdoor environments. While it can survive getting wet, it is not designed to be fully submerged underwater. Like any premium electrical system, installing it in a standard battery compartment (such as inside your RV or boat cabin) is the ideal way to ensure peak performance and maximize its 10+ year lifespan.
You can shop with absolute confidence. We back this battery with a solid 5-year warranty. All orders are shipped directly from our local warehouses in Europe (such as Poland and Germany) with fast, free delivery.
